Hamiltonian Lattice Formulation of Compact Maxwell-Chern-Simons Theory
Changnan Peng, Maria Cristina Diamantini, Lena Funcke +5
In this paper, a Hamiltonian lattice formulation for 2+1D compact Maxwell-Chern-Simons theory is derived. We analytically solve this theory and demonstrate that the mass gap in the…
Angular momentum quantum backflow in the noncommutative plane
V. D. Paccoia, O. Panella, P. Roy
We study the quantum backflow problem in the noncommutative plane. In particular, we have considered a charged particle with and without an oscillator interaction with noncommuting…
Quantum magnetic monopole condensate
M. C. Diamantini, C. A. Trugenberger, V. M. Vinokur
Despite decades-long efforts, magnetic monopoles were never found as elementary particles. Monopoles and associated currents were directly measured in experiments and identified as…
Fixing the non-relativistic expansion of the 1PM potential
Gianluca Grignani, Troels Harmark, Marta Orselli +1
We obtain a first order post-Minkowskian two-body effective potential whose post-Newtonian expansion directly reproduces the Einstein-Infeld-Hoffmann potential. Post-Minkowskian po…
Defect QED: Dielectric without a Dielectric, Monopole without a Monopole
Gianluca Grignani, Gordon W. Semenoff
We study a class of defect quantum field theories where the quantum field theory in the 3+1-dimensional bulk is a free photon and charged matter and the interactions of the photons…
Relating non-relativistic string theories
Troels Harmark, Jelle Hartong, Lorenzo Menculini +2
Non-relativistic string theories promise to provide simpler theories of quantum gravity as well as tractable limits of the AdS/CFT correspondence. However, several apparently disti…
